15.8 Spindle data
Introduction
The spindle mode of a machine axis is a subset of the general axis functionality. For this
reason, the machine data required to start up an axis have also to be set for a spindle.
The machine data to parameterize a spindle are therefore to be found under the axis-specific
machine data (from MD 35000 onwards).
Note
After the default machine data have been loaded, no spindle is defined.
Spindle definition
With the following machine data, a machine axis is declared to be an endlessly rotating
rotary axis whose programming and display is carried out modulo 360 degrees.
● MD30300: IS_ROT_AX (rotary axis/spindle)
● MD30310: ROT_IS_MODULO (modulo conversion for rotary axis/spindle)
● MD30320: DISPLAY_IS_MODULO (modulo 360 degrees display for rotary axis/spindle)
The machine axis is converted to a spindle by defining the spindle number x (with x = 1, 2,
...max. number of channel axes) in machine data
● MD35000: SPIND_ASSIGN_TO_MACHAX (spindle number)
The spindle number must be unique within the channel axes of the channel to which the
spindle is assigned.
